Given numbers are 787, 643, 231, 210

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(787, 643) = 506041

GCD(787, 643) = ( 787 x 643 ) / 506041

= 787 / 643

= 787

Step2:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 787, 643, 231, 210 is 1
